SPECIFlICATION formingpart of Letters Patent No. 698,413, dated April22, 1902.

` Application led July 5, 1901". Serial No. 67,207. (No model.)

To all whom it 11i/ty concern:

Be itA known that I, THOMAS A. SAVAGE, a citizen of the United States,residing atOarrollton, in the county of Carroll and State of Missouri,have invented certain new and useful Improvements in Car-Couplers, ofwhich the following is a specification.

My invention is a car-coupler, and relates to that class of couplersknown as the Jan Io ney type. f

In the aceompanyingdrawings, Figure 1 is a top plan view of the couplerwith part of the top of the draw-head removed in order to` show theinside mechanism. Fig. 2 is a front end view, the trip-lever removed andthe look-V block up. Fig. 3 is a frontend View, the trip-lever removedand the lock-block down. This is a modification of Fig. 2. Fig. 4 is alongitudinal vertical sectional view. Fig. 5 zo is a longitudinalsectional horizontal View showing the coupler unlocked. Fig. 6 is aperspective View of the knuckle and the lock` ing-arm. Fig. 7 is aperspective view of the pin and trip-lever. E

My invention is described as follows: l is a draw-head bifurcated at itsfront end and having in such bifurcated end and running back aconsiderable depth a recess 2. Running through the upper wall of saidre- 3o cess is an oblong rectangular opening 3, and

in the lower wall of said recess and immediatelyv under said rectangularopening is a depression or recess 4 `to receive the lower end of thecoupling-pin 5. The upper part of4 3 5 the said coupling-pin isrectangular and oblong in shape and has through its dat way a verticalslot 6, and in this vertical'slot is piv` oted a trip-lever 7. Thistrip-lever consists of a single bar of metal having a shorter .L bar 8extending at rightangles from this pivoted end, and in the free end is aperforation 9, and when this `coupling-pin 5 is in place and down thefront edge of the arm 8 rests against the front wall 10 of therectangular opening 3. On this coupling-pin and some distance below thetrip-lever is a shoulder 11, and this shoulder rests under a Steel plate12, that is secured to the under face of the upper wall of the recess 2,with its rear edge `on aline with the front wall of the rectangularrecess 3, so that when the said coupling pin is down this shoulder 1lrests under and is kept from moving up by said plate 12, and when thefree end of the trip-lever 7 is raised the right-angular arm 8 pressesagainst the front wall of the rectangular opening 3, and

this presses the pin back, and consequently Y the shoulder 1l out fromunder the steel plate enlargement 13, also an upper shoulder 14 and alower shoulder 15, and the extreme lower end of this coupling-pin isbeveled rearwardly, terminating in the edge 16, and hinged to theleft-hand wallof the recess 2 by an arm 18 is a locking-block 19, andthis lock- Ablock is provided with a vertical perforation 20,\andpassing through said perforation 20 is the said coupling-pin 5, andpassing through the wall of said perforation 20 and through aperforation 21 of said coupling-pin is a rod,

` and around this rod andagainst the rear face of the coupling-pin andthe front face of the rear wall is a spiral spring 22, which holds saidcoupling-pin against the front wall of said opening. Theresult of thiscombination is that the saidcoupling-pin may move rearwardly, and {thusbe raised; but it is never raised enough to allow its tapered end toentirely es- ,cape` from the recess 4, (see Fig. 2,) and the furtherresult of this combination is thatit only 1 operates in conjunction withthe lock-block- `that is to say, when the coupling-pin is raised thelocking end of the said lock-block is also raised, and when the lockingend of the said end of the right-hand wall 26 is bifurcated, and in thisbifurcation is a hinged knuckle 27, and in the free endof said knuckleis a recess 28, andrunning through the two parts of this knuckle is aperforation 29 to accommodate a neighbor coach that does not use theJanney'type, but uses the old-fashion the locking end of the lock-block,and consequently this arm 30 is held securely in place and the couplercannot be unlocked until the coupling-pin is raised. When said couplingis so raised, the lock-block is also raised, and then the said arm canescape, the knuckle liy back, and then the coupler is uncoupled. Whenthe couplingpin is raised to shoulder 15, said shoulder-pin rests on thefront wall of the recess 4, and consequently holds the lock-block up,and thus, as said above, the arln 30 is permitted to escape from underthe lock-block 19; but there is a finger 33 eX- tending from the eXtremeend of said arm 30, which is arrested by a stop 34, secured to the lowerwall of the recess 2, and this arm 30 is never allowed to escapeentirely from the said recess 2.

The lower face of thelock-block isp rovided with a tapering recess 35,so that when rthe locking end of said lock-block is down the arm 3l maypass into vsaid tapering recess, raise said lock-block, and pass beyondits end. As soon as this is done the spring 25 presses the saidlock-block down, and the coupler is locked, When the coupling-pin israised until the shoulder 15 rests against the lower wall of the recess2, the lock-block is held up, as shown in Fig. 2, in which case the arm31 is permitted to escape tripping the coupling-pin until the finger 33reaches the stop 34, and thus it will be seen that the lock may bereset, so as toremain in an unlocked position. In case it is desired tocouple the cars when the pin is set the finger 33 strikes against theenlargement 13 of the couplingpin 5, pushing the pin to the rear, andthus the pin and the lock-block descend and secure the arm 30 backagainst the wall of the said recess 2, (see Fig. 3,) and thus thecoupler is locked. The weight of the lock-block in connection with thepressure of the spiral spring 25 is such that the coupling-pin can underno circumstances be jolted out of its position no matter how rough theroad or short thecurves, and thus there is no danger of this cc'uplerbecoming accidentallyT uncoupled.

The spring 25 is especially adapted to coup- 1ers doing light work, suchas in street-cars, dac.; but where the coupler is made for heavy work,such as freight-cars and the like, the

weight of the lock-block will be sufficient without the spring 25. So invery heavy couplers I do not use the spring 25, and for this reason Icla-im the coupler Without the spring as well as with it and claim thecoup- 1er without the spring as a modification, as shown in Fig. 3.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-V 1 An automatic car-coupler, consisting of adraw-head having in its front enda recess, one of the side walls'of saidrecess being bifurcated at its front end; a knuckle hinged in saidbifurcation; an arm secured to the rear face of said knuckle, and havingits rear side beveled down nearly to an edge; a finger eX- tendingforward from the free end of said arm, said arm adapted to'lie close upagainst the inner face of one of the side walls of said recess; alock-block adapted to Work in said recess and hinged to the oppositewall, opposite the knuckle, and having in its lower face an inclinedrecess and a vertical rectangular perforation through its free end; aspiral spring, its lower end resting against the upper face of saidlock-block, and its upper end against the lower face of the upper wallof said recess; a stop secured to the opposite wall to which the knuckleis hinged, adapted to arrest the finger of the arm mentioned above; anupper wall provided with a vertical oblong rectangular opening; a platesecured to the lower face of said upper wall and parallel with the frontwall of said opening; a coupling-pin provided with aslot,and anenlargement at its lower end, forming an upper and lower shoulder and aperforation through its center; said coupling-pin passing through theperforation in the lock-block and rectangular opening; in the upperwall, its lower end resting in a depression in the lower wall; a boltpassing through said lock-block and the perforation in saidcoupling-pin; a spiral spring working around said bolt, and holding saidcoupling-pin against the front wall of said rectangular opening; atrip-lever pivoted in the slot of said coupling-pin, and adapted, whenraised, to throw the upper shoulder from under the plate secured to saidupper wall, thus permitting said coupling-pin and said lock-block to beraised, and the coupler unlocked, substantially as shown and describedand for the purposes set forth.

2. An automatic car-coupler, consisting of a draw-head having in itsfront end a recess, leaving two side walls, an upper and lower wall, oneof the side walls being bifurcated at its front end; a knuckle hinged insaid bifurcation; an arm secured to the rear face of said knuckle, andhaving its rear side beveled down nearly to an edge; a finger extendingforward from the free end of said arm; a lock-block hinged to the sidewall opposite the bifurcated wall, and having in its under face aninclined recess, and provided with a vertical rectangular openingthrough its free IOO IIO

end; the lower wall, provided; with a recess immediately under saidopening, astop se,` cured to the lower wall, opposite the hinged lknuckle, adapted to arrest the finger of said arm; the upper wall,provided with an oblongr rectangular opening; aplate secured to thelower face of said upper wall and parallel with the front Wall of saidopening; a

couplingfpin provided witha slot, a shoulder i below said slot, anenlargement at its lower end, forming an .upper and lower shoulder,

and a perforation through its center;` said `coupling-pin passingthrough the perforation in the lock-block and the rectangular 0pening inthe upper Wall; a bolt passing through said lock-blockand theperforation in said wall, thus permitting said .coupling-pin and saidlock-block to be raised, andthe coupler unlocked, substantially asshown, and described and forthe purposes set forth.
